4. 8 year old with stomach pain. Help.

Hello Doctor. Please find attached reports of my 4.8 old daughter who has chronic stomach pain wick gets relieved after gas passing or burping. She also has long belching episodes. We have treated her with two antibiotics and rantac in sep. Her tummy pain continues. Pl find attached blood reports and usg reports. I had submitted only usg earlier. Doctors say she may be under stress for attention etc and to ignore this without treatment. I'm not sure and think it may be gastritis and she needs help. She gets up in the morning with Tummy pain and this has continued. At least 5 times a day she says pain especially after eating. Advice please. I'll be grateful. Except for that value that I have attached her stool urine routine reports are normal. Cbc normal. Hb at 12.1, peripheral smear normal, sr amylase normal. Is this gastritis. Please help.
